Magnolia ashei is a species of flowering plant in the family Magnoliaceae, endemic to northwestern Florida. It is known commonly as Ashe's magnolia. It is sometimes considered to be a subspecies or variety of Magnolia macrophylla which occurs further north in the southeastern United States, but is now generally considered a distinct species. It was discovered in Okaloosa County, Florida by William Willard Ashe, and named after him by Charles Alfred Weatherby.
